. FIRE ESCAPE.

Application fiIed August a, 1926. Serial to. 128,038.

This invention relates to :[ire escapes, particularly to that class thcreol? which are adopted to be i'i'ianually extended, to serve windows adjoininga :lixed POlhiOll of the lire escape.

inasmuch as the Front upper niindoWs of a dwelling; are usually bed room windows, it desirable to have lire escapes opposite such windows for quicker-1t exist from a lmrning building, and on account of the lireescapes being thus put on the iliront of a building, it is important that the construction of the lire escape conform to the ornate appeainnce ol the building, rather than war the same, as is done by some common forms of lire escapes new in use.

lit is therefore one of the objects of this invention to provide a form oil? lire escape which Will serve as a balcony individually. to be in front of one or a smal l. group 0t Windows, and have extensions to be pulled. out like drawers of a table to come opposite adjoining; WllIClOWS or groups .o'l. \rii'ldows on either side oi? the fixed balcony.

liluch a lire escape will enable a person to leave thru. the window ol. a burning buildinn; and enter a Window of an adjoining building to escape in safety.

A. lurther object is to provide a lire escape "which can be attached. to a building in a simple and inexpensive 1n anner to materially reduce the cost oil? attaching the same to the building,

l l ith thee! and. other objects, my invention. resides in certain construction, one embodiment of which is illustratei'l in the d rawings is hereinafter described, its use'is ex;- plained and What 1 claim is set :torth.

ln the drawings Figure l is a front elevation of a fire escape embodying; my invention.

l1 igure 2 isa fragmental top plan of the tire escape shown in Figure 1. r

section taken on. the

Figure 3 is a vertical line (l-hot Figure 1. p

l ignire 4t is an enlarged vertical section of a part oil, the lixed and sliding frames assembled therewith.

Figure 5 is a front elevation of: a part of a building front, showing two balcony lire escapes, embodying my invention and. at ranged to accommodate six Windows in a row.

Like ignites oil. reference refer to like parts. in the figures, there is shown a fixed platforn'i frame 10, formed by channel irons ll and Ql; fixed to its ends.

and 12, with slats 18 fixed or riveted thereto, and fixed to Wall. brackets 14- and. 15, which consists oi? angle irons 16 and 17 fixed to the Wall 18, and riveted together. The brackets 141; and 15 extend beyond the channel iron. ll, to form an extended support for the braeei l9 and 20, rospectivelv, ivhich are riveteijl thereto. Vcrtical'slats 2]. form the front wall. of the lire escape and are fixed at thetop to a tube 22, Which has caps 522-5 The end slats and are liked to the respective braces ill and 20.

Within the lined liraine forined by the channel irons Hand 12; is a, sliding frame 27, torined by the angle irons 28 and 529, to which are fixed the slats 30. The angle irons 28 and 29 rest upon rollers ljh vhieh enter notches in the bottom flange ol. the channel. iron 11 and are mounted pivotally upon the b 'aclcets 32 which are riveted to the channel irons 11. The angle irons and Bil ride upon their ed ,7 es on the rollers 31. The sliding frame 27 is ll-shaped, having a cross angle iron 38 fixed to the outer ends of the angle irons 28 and i To the eroas angle iron 33, is fixed a pipe rail 34, which has a vertical portion parallel with the Wall. 18, a horizontal portion 236, perpendicular to the wall l8, and a horizo11- tal portion 37, parallel to the Wall 18, in sliding engagement With the cap 23 and on tering the tube 522. Upon the inner end of the pipe rail 34:, and in sliding engagement with the tube 22, a flange Sill like l to the rail 34L. Between and fixed to the rail portion 86 and the cross a lo ironiil are slats ill), 'lorn iino' an end Wall th the lire escape.

Out of the opposite end o'l the platform frame 10, projects a. sliding iliraine 4H), which is lLshaped, having angle irons 4.1 and 1-52, riding with their flan l3 upon the rollers 31, and having the :u'igle irons 415i and l2 connected by slats at. The angle irons ll and. 4-2 are connected at their outer ends With the cross angle irons 4-5. The angle irons 4t]. and t2 lie closely within the angle irons 28 and. 29, while the angle irons 2t; and 29 lie closely Witl'iin the channel irons l1 and 12, as shown partici'llarly in the enlarged section or Figure 4;. All angle irons and channel irons that slide Within oneanotlu-ir are parallel.

To the cross angle iron is lixed a pipe rail 46, which. has a vertical portion 45? parallel Withv the wall 18, a horizontal portion 48, perpendicular to' the wall 18 and a horizontal portion 49 parallel with the wall 18, and in sliding engagement with the cap 24 and entering the tube 22. Upon the inner end of the pipe rail 46, in sliding engagement with the inside of the tube 22, is a flange 50, fixed to the rail 46. Between, and fixed to the rail portion 48and the cross angle iron 45, are slats 51, forming another end wall to the fire escape.

In Figure 5 are shown six windows 52, 5,3, 54, 55, 56 and 57. V Opposite the windows 53 and 56 are fire escapes 58 and 59, similar in construction to the one above described and illustrated in the other figures. The sliding frames which can be drawn out of ends of the fire escape are shown in extended positions by the broken lines 60 and 61,

and 62 and 63. Thus one extension at 60 comes opposite window 52, when drawn out by pulling on the rope, cable or chain 64. p The extension at 61,7comes opposite window 54. The extension at 62 comes opposite the window 54. The extension 62comes opposite the window 55. The extension 63 comes opposite the window 57, pull lines 65, 66

V and 67 being provided for the extensions at 61 62 and 63. These extensions are supported on the cantilever principle, when they are drawn out. When they are pushed in, they form closed ends to the fire escape which then appears as a balcony.

A building having a row of windows, can be provided with such fire escapes for every third window, and the extensions will accommodate the remainin two-thirds, effecting a considerable saving in construction, as well as on the cost of mounting the fire escape.

Although no means are shown upon which to descend from the fire escape, any suitable means can be provided for the purpose but it would bepreferable'to use some means which can be folded or rolled up in a. small space, rather than a fixed ladder, if it is desired'to have the fire escapes show as individual'balconies on the face of the building.

While I have shown only one embodiment of my invention in the drawings, other forms'can be devised for the purpose, without departing from the spirit and scope of my invention. I therefore do not wish to be confined to the one embodiment thereof herein shown and described.
